Title: Visible scale of the sound volume at the telephone
Inventor: TRON KRESZENZIA
IPC: H04M1/62
Filed: 1987-07-15
Abstract: So that the ringing of the telephone at an undesirable time does not cause a disturbance but one is still available at any time, this visible scale brings great relief for everybody. This visible scale can be attached to any telephone. The sound volume indicator must be controlled from the volume control. The indicator must be in the green field in the case of "quiet", in the yellow field in the case of "medium" and in the red field in the case of "loud". The result is that the sound volume can be rapidly recognised and also easily set. Particularly for old people and those with impaired vision who are particularly dependent on the telephone.

Title: Helical compression spring for a motor-vehicle suspension
Inventor: TAUTENHAHN WOLFRAM DIPL ING
IPC: F16F1/08
Filed: 1987-08-26
Abstract: The invention relates to a helical compression spring for motor vehicles which has a partially progressive characteristic and consists of two integrally connected parts. In order to provide a favourably dimensioned spring which is, in particular, well suited, in the case of a driven axle with a driving half-shaft leading to the vehicle wheel, to being arranged as close as possible to the wheel, that part of the spring which is arranged on the body side is of barrel-shaped design and the wheel-side part of the spring, which is arranged axially relative to the first-mentioned part, is of cylindrical design, the coil diameter of the cylindrical part of the spring being significantly smaller than the maximum coil diameter of the barrel-shaped part of the spring. The helical compression spring is in other respects designed so that decoupling of coils involved in a spring action takes place so as to achieve the progressive part of the characteristic at the spring support on the body side. <IMAGE>

Title: Method and arrangement for determining abnormal anatomic regions in a digital X-ray photograph (image)
Inventor: DOI KUNIO
IPC: G06T7/00
Filed: 1988-07-30
Abstract: A method and an arrangement for determining and displaying abnormal anatomic regions in a digital X-ray photograph produces from the digital X-ray photograph signal-amplified image data having a maximum signal-to-noise ratio and signal-suppressed image data having a suppressed signal-to-noise ratio. Differential image data are obtained from these image data by subtraction, in order to remove low-frequency, structured anatomical background which is essentially the same in the signal-suppressed and the signal-amplified image data. After the structured background is removed, features are obtained. In order to detect lumps in the lungs, processing of the pixel threshold values is carried out, followed by a test for circularity and/or magnitude of the determined, closely adjacent pixels. The magnitudes of the threshold values are altered and the effect of this alteration on the circularity and magnitude is used as an indication of lumps. In order to detect mammographic microcalcifications, processing of pixel threshold values and processing of threshold values of the region are carried out for adjacent pixels. Groups of suspect anomalies are then established.

Title: Device and method for propagating or breeding queen bees
Inventor: EPPLER THEOPHIL
IPC: A01K49/00
Filed: 1988-08-24
Abstract: Method of propagating or breeding queen bees taking into account the flow of information within the breeding receptacle. A secondary effect is that the queen bee larvae are less exposed to danger by the varroa mite. In this method and this device for breeding queen bees in the queenright bee colony, the breeding receptacle (1) is separated by means of a separation mesh (2) which cannot be penetrated by bees to form an information space and a space for brood care. The functional information is transmitted by the bees in the information space through the separation mesh to the bees in the space for brood care. Queen bees which are bred by this method are queenright. The acceptance figures achieved in this method according to the invention over the entire breeding period are considerably higher. Moreover, since there is a constant turnover of brood, the queen bee larvae are endangered much less by varroa mites than in the previously known method, where brood is constantly running out, thus releasing large amounts of mites which find no host to parasitise other than the queen bee larvae, which they then can damage extensively. <IMAGE>
